My invention relates to rcin'torcemcnts for battery plates.

In an elect i0 storage battery. especially of the type wherein a seriesof loacl plates are immersed in an electrolyte with interveningseparator sheets of wood it is common occurrence for the plates tohackle through overheatingor other causes thereby pinching" through thewood separator sheets and short cirouiting. i

It is the object of my invention to provide a means wherehy the saidseparator sheets of Wood may be associated with separating" elements soformed and constructed as to etltectively reinforce the erlgrs andllOtly o't each plate whereby to prevent distortion oil the same Withoutinterfering with the action thereof.

la the drawings:

Fig. 9 is a perspective View of one portion of the wood separator plateused in noninn tion with the rein forcing element sho W11 in Fig. 1.

Fig. 3 is a plan view of three hattary plates fitte with the separator'lorming the basis of this invention.

A frame 2 circlesthe plate covering a narrow strip of the same contiguous to its outeredge anrl preferably having" its outer edges tlush with the outer edgesof sairl plate as shown at 3. This iramc is pre'fe-raliily made ofvulcanized rubber or any other suitable material of suttleientstrengtl'i anti rigidity to resist the warning temlcncics of the plateswhen heatctl. ll: prefer also to connect two of the oopositecorners ot'the irame 2 with a cross meniher 4: to rcinh'iroc the c ntral Portion otthe same. These members 2 and 4 are provirled with grooves as 5 topermit the proper circulation at the electrolyte.
